Cleaning the Platen Glass and Document Cover
Important
Be sure to turn off the power and disconnect the power plug before cleaning the machine.
- The power cannot be turned off while the machine is sending or receiving a fax, or when unsent faxes are stored in
the machine's memory. Make sure if the machine completed sending or receiving all the faxes before
disconnecting the power plug.
- The machine cannot send or receive faxes when the power is turned off.
- If the power plug is disconnected, the date/time settings will be reset and all documents stored in the machine's
memory will be lost. Send or print a necessary document, or save it on a USB flash drive before disconnecting the
power plug.
Do not use tissue paper, paper towels, rough-textured cloth, or similar materials for cleaning so as not to scratch the
surface. Be sure to use a soft and dry cloth.
Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the machine,
as this may cause a malfunction or damage the surface of the machine.
With a soft, clean, lint-free and dry cloth, wipe the platen glass (A) , the inner side of the document cover (white sheet) (B) ,
the glass of the ADF (Auto Document Feeder) (C) , and the inner side of the ADF (white area) (D) gently. Make sure not to
leave any residue, especially on the glass surface.
Important
The inner side of the document cover (white sheet) (B) is easily damaged, so wipe it gently.
If any foreign substances such as glue, ink or correction fluid are adhered to the glass of the ADF (C) as shown in
the figure above, some black streaks will appear on the scanned image.
In this case, wipe the dirt off gently.
